Purchased 3 15ml bottles of BioSil from Amazon Marketplace supplier for $76.64. All from the same lot and expiration of Sep 2016.

Product should be consistency of water and be dispensable by the drop when bottle is squeezed. First bottle was OK for initial 5-6 uses. Then it suddenly became the consistency of molasses. Now unable to dispense in the recommended 5 drops because it comes out in a thick string.

Check of remaining two bottles revealed same deterioration of the product. I have no way of knowing if it is even still effective or if some erroneously included ingredient caused the problem. So I must dispose of approximately $75 worth of BioSil. Note that 12 months remained until the expiration date.

Call to company yielded no satisfaction. They requested I pay the postage to mail it to them for testing. I requested prepaid mailing label but it was not provided.

No replacements offered. No satisfactory resolution provided.

DonnaPic wrote the review because of damaged or defective at Natural Factors and attached a photo. Reviewer claimed that he or she lost $75 and wants Natural Factors to "three replacement bottles".

Author liked the most prompt call back. The author asks this business to immediately contact him/ her to briefly discuss his/ her negative experience with the company.
